Ankle instability typically results from inversion injuries, where the foot rolls outward after landing on uneven surfaces, causing pain, swelling, or bruising. While most cases improve with physiotherapy, recurring injuries can signal deeper issues, such as joint damage and a risk of arthritis. Persistent symptoms like deep ankle pain, swelling, and instability warrant medical evaluation. Treatments include minimally invasive procedures like ankle arthroscopy or ligament reconstruction, offering effective solutions for lasting stability.
